A federal judge has denied a request by retailers Winn-Dixie and Bi-Lo for additional discovery in the mushroom price-fixing antitrust litigation.

U.S. District Judge Berle Schiller of the Eastern District of Pennsylvania’s ruling relates to the plaintiffs’ request for the defendants—members of the Eastern Mushroom Marketing Cooperative—to produce documents on mushroom sales. Schiller granted leave for the plaintiffs to refile.
